[0027] A drive transmission component includes a driving shaft 4 and a driven shaft 5. Both ends of the driving shaft 4 and the driven shaft 5 penetrate the side wall of the processing chamber 1 for rotation. One end of the driving shaft 4 is fixedly connected to the output shaft end of the motor 2. One side of the driving shaft 4 penetrates and is fixedly connected with a driving wheel 6. A transmission belt 7 is rotatably sleeved on the surface of the driving wheel 6. The inner wall of the transmission belt 7 is rotatably connected with a driven wheel 8. One end of the driven shaft 5 is fixedly connected to the side surface of the driven wheel 8. The surface of the driven shaft 5 penetrates and is fixedly connected with a driving wheel 9. The steel plate is driven to move by the driving wheel 9, and the steel plate is immersed in the coolant for sufficient cooling.

[0028] Furthermore, the bottom of the support 11 is fixedly connected to the base plate 12, the top of the base plate 12 is fixedly connected to the recovery bin 13 and the cooling pump 14, the recovery bin 13 and the cooling pump 14 are connected by a water pipe, the side of the cooling pump 14 away from the recovery bin 13 is fixedly connected to a connecting pipe 15, the upper end of the connecting pipe 15 is fixedly connected to a connecting cover 16, the side of the connecting cover 16 away from the connecting pipe 15 is fixedly connected to the opening of the liquid inlet 22 on the outer side of the processing bin 1, the recovery bin 13 is located below the liquid outlet 23, the recovery bin 13 recovers the coolant, and cools the steel plate again after being cooled by the cooling pump 14.

[0029] Furthermore, a support plate 17 is fixedly connected to one side of the processing chamber 1 away from the connecting cover 16, a pillar 2 18 is fixedly connected to the bottom of the support plate 17, a bottom of the pillar 2 18 is fixedly connected to the top of the bottom plate 12, a through groove 24 is opened in the middle of the support plate 17, and the support plate 17 supports the steel to facilitate subsequent transmission.

[0030] Furthermore, a mounting groove 19 is opened on one side of the top of the processing chamber 1, and connecting shafts 20 are rotatably connected to both sides of the inner wall of the mounting groove 19 through bearings. A roller 21 is fixedly connected to the middle of the connecting shaft 20 to facilitate the steel plate to slide smoothly into the processing chamber 1.

[0031] Furthermore, spoilers 10 are fixedly connected to both sides of the driving wheel 9 to stir the coolant in the processing chamber 1 so that the coolant is evenly mixed.

[0032] Furthermore, the side surface of the driving wheel 9 is provided with anti-skid grooves to prevent the steel from slipping during transportation.

[0033] Furthermore, the top of the support plate 17, the top of the drive wheel 9 and the bottom of the inner wall of the liquid outlet 23 are flush with each other, so that the steel plate and the heated coolant are discharged through the liquid outlet 23, and the liquid level of the coolant in the processing chamber 1 is higher than the opening of the liquid outlet 23.

[0034] Through the above technical solution:

[0035] The special steel plate is transmitted to the side of the processing chamber 1 through the existing transmission equipment. The bottom of the steel plate first contacts the top of the roller 21, and then slowly slides onto the driving wheel 9 in the processing chamber 1. The motor 2 drives the driving shaft 4 to rotate. At the same time, it also drives the driven wheel 8 and the driven shaft 5 to rotate through the driving wheel 6 and the transmission belt 7, so that all the driving wheels 9 in the processing chamber 1 rotate synchronously to transport the steel plate to the side of the support plate 17. The recovery chamber 13 is filled with coolant. The cooling pump 14 sucks the coolant in the recovery chamber 13 and cools it down. After that, it is discharged into the processing chamber 1 through the connecting pipe 15, the connecting cover 16 and the liquid inlet 22. Since the opening of the liquid outlet 23 is smaller than the liquid inlet 22, the outflow speed of the coolant in the processing chamber 1 is less than the inflow speed, so that the liquid level of the coolant is higher than the top of the opening of the liquid outlet 23, and the top of the steel plate and the top of the inner wall of the liquid outlet 23 are close to each other. The steel plate is flush with the bottom, so that the steel plate is completely immersed in the coolant. The coolant absorbs the heat of the steel plate and is heated up, then discharged through the liquid outlet 23, passes through the through groove 24, and falls into the recovery bin 13 for recovery and cooling. The cooled steel plate is moved out from the liquid outlet 23 to the support plate 17, and then the existing conveying equipment takes the steel plate out and transports it to the next equipment to complete the tempering heat treatment. By setting the processing bin 1 and the driving wheel 9, the surface of the steel plate is fully in contact with the coolant, the contact area is increased, the contact time is prolonged, and the coolant in the processing bin 1 is kept in a flowing state, and is discharged in time after heating to avoid a decrease in absorption efficiency. The problem that the steel surface is not in sufficient contact with the coolant due to the reciprocating swing of the nozzle to spray water for cooling, the coolant cannot completely cover the steel surface, and the steel is not in contact with the coolant for a long enough time, resulting in an insufficient cooling effect.

[0036] By setting the spoiler 10, when the driving wheel 9 rotates to transport the steel plate, the spoiler 10 follows the driving wheel 9 to rotate and stir the coolant in the processing chamber 1, so that the coolant is mixed more fully, avoiding local overheating that causes a decrease in the heat absorption effect, and further improving the cooling effect.

[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
